This project gives you a chance to contribute to the learning of all your
classmates. You will research and report on a scientist who made a
significant contribution to the Earth Sciences. Your report will consist
of a poster outlining your scientist's contribution to our understanding of how
the world works along with a 5 minute oral presentation. For help finding

Major Concepts in This Unit:
Expressing Scientific Information
- How do observations differ from inferences?
- How can we use classification skills to organize information?
- How are measurements expressed in SI units (metrics)?
- How can very large (and/or very small) numbers be expressed in powers of ten?
- How can scientific notation make it easy to estimate?
Graphing Skills
- How can complicated data be presented in an easy to interpret format?
- What are the different types of graphs?
- What type of data is best represented by each graph type?
- How can graphs be used to predict the outcome of an experiment?
- How can rate of change be calculated?
Density and its application to Earth and Space Systems
- What is density?
- How is density determined in the laboratory?
- On what factor(s) does density depend?
- How do materials of different densities interact with each other?
Skill: Calculating and Reducing Experimental Error
- How can experimental error be calculated?
- What is an acceptable degree of error in the laboratory?
- How can experimental error be reduced?
